JWt (Java Web Toolkit) is a library for developing accessible and interactive Web applications with an API that is widget-centric and inspired by desktop GUI APIs. To the developer, it offers abstraction of Web-specific implementation details, including graceful degradation. Under the hood, the library uses the latest techniques when available to handle events and update the user interface.

Template Data Interface (TDI, /ʹtedɪ/) is a markup templating system written in Python with (optional but recommended) speedup code written in C.
Unlike most templating systems, TDI does not invent its own language to provide functionality. Instead, you simply mark the nodes you want to manipulate within the template document. The template is parsed, and the marked nodes are presented to your Python code, where they can be modified in any way you want.

P* (P-star) is a Web programming language that incorporates common tasks like template handling and database queries into the language. It features MySQL database access with prepared statements, HTML templates, standard arithmetic and variables, functions, structs, (to-be-classes), JSON output, and GET and POST. Programs can be run on the command line, in a CGI environment, or by the P* Apache Module.

LightAdmin speeds application development by bringing a pluggable, fully operational data management backend to JPA-based applications and relieving your codebase for more important things. It allows developers to define a data management backend with POJOs and JPA and customize it using simple Domain-specific language.

Diligence is a collection of ready-to-use code that helps you tackle much of the dreary work required for building massively multi-user Web applications. It relies on and fully embraces Prudence (the "Savory JavaScript" flavor) and MongoDB, two platforms designed from the ground-up for REST-friendly scalability. With Savory you can quickly get users logging in, accessing data with permissions, subscribing to email notifications, shopping and paying you, interacting with each other, and managing their own content on your site. It lets you cleanly integrate with third party technologies and services, from Ext JS and Sencha Touch to Facebook.

Vega is a GUI-based, multi-platform Web security scanner that can be used to find instances of SQL injection, cross-site scripting (XSS), and other vulnerabilities in your Web applications. It also includes an intercepting/scanning proxy for interactive Web application debugging and fuzzing.

BEdita is a Web development framework that comes with a full-featured content management system out of the box. BEdita 3 is a solid software environment, fully compatible and respectful of Web standards. The user interface has been developed in accordance with well-established rules in usability and ergonomics, but it is also practical and enjoyable. BEdita has been built upon CakePHP, the well known framework, from which it inherits the MVC design pattern. Moreover, a number of third party libraries and tools have been used, like JQuery, Smarty, and so on.

ZK is a highly productive Java framework for building amazing enterprise Web and mobile applications. With event-driven components and an XUL-based markup language, developing is as simple as programming desktops and authoring HTML. Scripting languages include but are not limited to Java, JavaScript, Ruby, and Groovy.
